To all whom it may concern: I

Be it known that I, ELFORD F. 1300mm, a citizen of the United States,residing at Torrington, county of Litehfield, State of Connecticut. haveinvented an Improvement in Bread \Vrapper-Sealing Machines, of whichthefollowing is a specification.

This invention has for its object to provide a simple and inexpensivemachine for end and bottom sealing the wrappers of loaves of bread.

It is of course well understood that custom requires that loaves ofbread be independently wrapped in wax paper. The sheets of paper afterbeing wrapped about the loaves require to be secured which has been doneboth by the use of string and by heating the wrappers and melting thewax therein so that the flaps of the wrapper will adhere together. Thissealing operation has been heretofore performed, so far as I am aware.by complicated and expensive ma chines requiring either gas or electricconnections. In lieu of these complicated machines I have. devised amachine so simple in construction and operation that it can be producedat triliin z expense, cannot get out of repair and can be used by anyperson skilled or unskilled, thus placing it within the reach of'smallbakers and enabling them to effect an important saving of time andexpense over tying the wrappers with string and enabling them to quicklyand effectively seal each wrapper.

In the accompanying drawings forming a part of this specification,Figure 1 is a. perspective of my novel machine; Fig. 2 a per spective ofa loaf of bread wrapped and scaled; Fig. 3 a perspective of one of theslug holders detached: Figs. 4 and 5 detail views on an enlarged scaleillustrating: a simple and convenient means for detachably securing theslug holders to be sealing 'ilatcs; Fig. 6 a transverse section ot thema chine on the line indicated by 6 in Fig. 1, looking in the directionof the arrow; Fig. 6 a detail view corresponding therewith showing ascaling plate inclined from the bottom outward instead of standingvertical to the bed; Fig. 7 a transverse section on the liueindicated by7 in Fig. 1, looking in the direction of the arrow: Fig. 8 a verticalsection on the line indicated by 8-8 in Fig. 7, looking in the directionof the arrows, and Fig. 9 is an enlarged detail sectional viewillustrating a practical mode outward from the of constructing the slugholders and the drawer.

1O denotes the frame or body of t chine which may be made of wood andmay be placed upon a table or otherwise con vementl supportw'l. Over theframe and secured thereto a bed 11 of sheet metal.

12 denotes the adjustable sealing lates be tween which the loaves ofbread c passed cndwise, and which may stand vertically" to the bed, asin Figs. 1, and T, or mav in line vertica plane, as in Fig. (3,depending upon whether the ends oi the loaves to be operated upon areparallel ta; each other or inclined outward iron. each other. Thescaling plates may be formed integral with or rigidly secured to bases3.3 which are adapted to be moved ina'arti or; outward ov r the l ed. heter c oi the bases are attached in any suit .hman nor to carrying pieces14;, as by P1?! of Screws 1;"; which pass through top strips 1 3 andengage the carrying 49965.

lho cm 4 in: pieces have respectively right and left threaded engagementwith shafts 1? which pass transversely t-ino'iign the frame and are heldagainst long tudinal ins'wenicnt in any suitable manner as by means cl18 on the shafts which bear against plates 19 on the fra .ie. Thecarrying pie ar shown as provir ed with nutallio lxeariugsfi ll whichare engaged by the thieudfi; of the shafts. One or both ends of the axeprovided with linger wheels 21 for some?! icncc in rotating the shaftsto adiast the sealing plates toward or from each o-Y's over the bed.

In my novel machine the heating: o t wrappers to rii'e t end and bottom5 i1 5 thereof is eliecl'cd it; me" s at rl 22 which are held i l jflfliliiti with the plates and with the under side of These slugs may bemade terial that will not part with in idly. for example i rifl's. As e-3r must have an men. it follows that may be hen l th rein whip-out a.cost. The p fo nd cilnr z of We wrap 'iors arc placed in the solo s 1'5.whi h are simply boxes with one s de emo ed which muv be in of wood or nfai as fol-red and are lined with asiu suitable heat r sist" matcrl: byill in Fig. 2 Tue slug: h li plates in 1! attached to the scalin ablemanner. in ile present instance transversely between the scaling shownthe holders as provided with headed pins 25 which engage slots 26 in thesealing plates and retain the holders in place, as clearly shown in Fis. 1 and 4. The slugs project from the hol ers sufficiently to causethem to lie in close contact with the plates and impart heat: thereto.

The bottom sealin of the Wrappers is effected by means of s ugs placedin a drawer 27 which slides in ways 28 secured to the frame. Springs 29upon the ways act to raise the drawer and retain the slugs in contactwith the under side of the bed, the frame being cut away as shown, toreceive the drawer. The drawer is preferably lined with asbestos orother heat resisting material in the same manner as slug holders 23. Thereceiving end of the machine is toward the left, as seen'in Fig. 1. Itwill be noted that the sealing plates flare outward at their receivingends to permit the wrapped loaves to be' conveniently inserted. Theoperator places the wrapped loaves plates with the bottoms of the loavesresting on the bed and the ends bearing against the sealing plates whichare adjusted sumciently close to each other to press the end flaps ofthe wrappers down tightly but at the same time permitting the loaves tobe pushed ahead as succeeding loaves are placed in the machine, thefeeding being by hand. As the bottom folds of the wrappers pass over theportion of the bed directly over the drawer, they will be heated bv theslugs in the drawer sufliciently to melt the wax in the wrappers andcause the overlapping edge at the bottom to adhere to the ply'of paperunder it. The portions of the sealing plates contiguous to slug holders23 are heated by the slugs in the holders and the wax in the end flapsof the wrappers is melted and said flaps are causedto adhere to theflaps under them, as indicated in Fig. 2. Each wrapped loaf as it ispushed forward to be sealed, pushes the loaves ahead of it forwardbetween the sealin plates, which are extended some distance eyond theslug holders so that the relatively cool forward ends of the sealingplates will partly cool the sealed end flaps and the relatively coolportion of the bed forward of the drawer will partly cool the sealedbottom flap so that before the'loaves pass from the machine, thesealings of the wrappers will have become sufliciently cool and set topermit the loaves to be handled without danger of breaking open thesealings.

Having thus described my invention I claim:

1. A machine of the character described comprising a metallic bed,metallic sealing plates between which the wrapped loaves are passed, adrawer for heated slugs adapted to slide underneath the bed, and holdersfor heated slugs having one side removed and adapted to be placedadjacent to the scaling plates with the slugs in contact therewith.

2. In a machine of the character described, the combination with ametallic bed and metallic sealing plates, of slugs adapted to be heatedand holders for said slugs having one side'removed. said holders beingadapted to be placed adjacent to the surfaces to be heated with theslugs in contact with said surfaces.

3. A machine of the character described, comprising a metallic bed,metallic sealing plates between which the wrapped loaves are passedendwise, a. drawer for holding heated slugs lying under the bed, waysfor said drawer and springs in the ways whereby the drawer is raised toretain slugs in the drawer in contact with the bed.

4. A machine of the character described comprising a metallic bed,metallic sealing plates between which the wrapped loaves are passed andwhich are provided with slots and holders for heated slugs having headedpins for engagement with said slots whereby the holders may be.detachably secured to the sealing plates, for the purpose set forth.

In testimonv whereof I affix my signature in presence of two witnesses.
